to provide a strong base to w-hiel the opcrating mechanism seemed; to, provide rail expansion arresters;, e to provide a crossing which allows a passing of a train at a very high speed; the invention consisting in the construction, combination. and arrangement of devlces hereafter more fully described and claimed, and illustrated in the accompanying drawing, in which- Figure 1 is .a top View of my devlce.

The base plate 1 is constructed to receive the rails 2, 3, 4L, 5, 6, 7, 8 and;9. Rails 10, 11, 12 and 13 are formed onthe base plate 1 alining with the first named rails. A

strong support for the operating mechanism is formed in the four armed spider 14, being secured at its ends to'the base platel. A vertical cross-sectlon through the spider is shown in Fig. 3, a'heavy center-pivot 15 being'secured in the center of the spider, this being at the same tlme the center of the four. rails, forming a crossmg.

Fig. 2:5. .Thewdifierent levers. are connected wlth the operatlngdisks 16, by

the connecting rods 26, 27, 28 and 29 re spectively. Operating rods 30, 31, 32 and 33 are also connected to the operating disks 16.

A pulling on the rod 31 causes the disks 16 toturn around the pivot 15 in a right hand. direction, the Fig. 2 illustrating the position which is obtained after such pulling. The pulling on the rod 33 causes a turning of the disks 16 in the same direction, this showing that the passing of a train in either direction on a certain track will cause the setting of the rail-pivots to aline with the track on which the train is passing. a

The passing train causes a pulling on the rods 30, 31, 32 and 33 by rushing against the lever 34 mounted betweenrthe rails of each track, see Fig. 1. The lever 34 is shown in Fig. 7 in detail, being secured to a shaft 35, the lower end 36 being connected to the operating rods. The shaft 35 is journaled in clamp bearings 37, detailed in Fig. 8. Levers of this kind are mounted between the tracks a suitable distance before each cross a ing. The operating of the levers mounted. between the rails of the track running in one 105 certain direction causes the levers between the rails crossing the first track to move back to the original position, ready to be operated ',ta 1le'd.in F1g.-:7-."- The operat ng rod end'42 ';in Fig. 7 terminatesin' 'a sleeve 39 whichfis fing'rods fandi3 2wi11 cause the operating.

Thewhole device will be mounted on a strong concrete foundation, and as all mechanism is rigidly connected to the base, the automatic operation of this device is posi- V tive.
